Let me know...what I did is went on the RD website and joined there using my name and my company's name. If you are accepted (normally with a company name it's a cinch you will) you will get a welcome letter and I.D number. Just take that letter with your Tax exempt form from your company to the customer service clerk. You will need a resale certificate from Ma. I just said I forgot mine and the clerk printed me up one already filled in I signed the cert. and she gave me two membership cards. Really easy when you sign up online. Good Luck
